During Months 19 to 32, SOTERIA partners advanced the development, testing, and refinement of road safety solutions for VRUs across the four LLs in Germany, Greece, Spain, and the United Kingdom. Building on the co-creation foundations laid in the first phase of the project, targeted stakeholder engagement continued through workshops, surveys, and pilot demonstrations. New user groups such as motorised courier driverss and shared e-bike users were included, and feedback from over 2000 individuals informed refinements to solution specifications and use cases.The integrated SOTERIA platform matured significantly, with enhanced modules for accident analysis, safe routing, and situational awareness. The Safe Mobility Data Space (SMDS) was upgraded with 22 new datasets and 9 smart data models covering accident hotspots, harsh driving events, and travel demand. Comprehensive Knowledge Archive Network (CKAN) and Eclipse connectors were deployed to support secure data sharing. The labelled graph and visualisation dashboard were expanded to include temporal and user-specific safety indicators. Accident prediction capabilities were strengthened through the deployment of deep learning models and generalised linear models (GLMs). These models incorporated connected vehicle data and travel demand segmentation to estimate accident frequency and severity across road sections and intersections. The XAI module was updated to ensure transparency and interpretability of predictions, using techniques such as GNNExplainer and GraphLIME. Two sensor kits were upgraded to capture motion, environmental, and proximity data from micro-vehicles. These kits, along with the REBO dashcam system, were deployed in the SOTERIA netowrk of eight European cities to collect real-world data on near-misses and hazardous conditions. The data supported the development of the speed advisory module, which provides real-time alerts to VRUs based on road and environmental risks. A suite of safety services was implemented, including the micromobility hazard mapper, protective equipment assessment module, and a nudging engine that delivers multilingual, context-aware safety messages. The mobile application was redesigned with improved user interface / user experience, accident hotspot overlays, and journey logging features to support user engagement and impact tracking. The first round of demonstrations was completed in all LLs, validating seven core solutions (measures) and informing improvements for the second round. Dissemination activities expanded the stakeholder network while there were over 10 000 website visitors and 500 social media followers. Two national patents were granted, and an EU patent application was filed. Policy recommendations were drafted through a stakeholder workshop, aligning SOTERIA outcomes with Vision Zero goals and Sustainable Urban Mobility Plans.
